How to troubleshoot an iPhone sensor yourself. IPhone touchscreen does not work or works poorly - here is the fix for iPhone 6 s touch screen does not work

Twitter

The screen does not respond to your touch, the touchscreen becomes dull and freezes: remember if your phone has fallen recently? This may be the reason for the poorly functioning sensor on the iPhone 6, 6s.

In addition to the fall, the performance of the touchscreen is affected by:

screen replacement;
software update;
moisture getting inside the device;
screen dirty.

Experts believe that you should contact a service center if:

the sensor responds, but with a delay;
The phone’s “reaction” is missing in some places on the screen;
The touchscreen doesn't work at all;
The device lives its own life: it opens and closes applications on its own, types text, and turns off.

Important! If the gadget does not respond completely to touch, then there is a possibility of a motherboard failure. It is necessary to urgently contact specialists.

What not to do and how to solve the problem yourself

In order to save money, advanced users want to fix gadget problems themselves. When trying to “reanimate” the touchscreen, you should not follow “harmful” advice:

Dry your iPhone with a hairdryer if it falls into water;
without outside help, glue or replace the screen if it comes off;
disassemble and assemble the “mobile phone”;

This will increase the cost of repairs, but will not save the situation.

3 ways that you can take without being a specialist in the field of electrical repairs:

Perform a full reboot of the device (Press 2 buttons simultaneously for 20 seconds: power and home);
remove the protective glass or film. They may be the reason why the sensor does not work on iPhone 6, 6s plus;
Wipe the display from dust and dirt.

Important! Do not try to replace the screen on your iPhone yourself, because if you damage important parts, the repair will cost more. Only an experienced craftsman can perform such work. Our service center offersaffordable prices in St. Petersburg for replacing iPhone 6 glass.

If the sensor on an iPhone does not work, then it is impossible to use the device normally. You can fix the problem yourself, but only if it is of a software nature. For mechanical problems, it is recommended to contact a service center.

Reasons for incorrect sensor operation

We have already talked about. In the latest versions of the iPhone, they remain the same: the entire screen, certain areas do not work, the touchscreen responds to touch with a delay or takes on a life of its own. The appearance of these factors is associated with one of the listed (or complex) reasons:

Screen dirty.
Poor quality protective film or glass.
Problems with the software.
Incorrect sensor calibration.
Controller error.
Mechanical damage due to impact or fall, water ingress.

If the touchscreen does not respond to touches at all, this may be due to sensor failure, controller failure, or defects in the motherboard.

Troubleshooting

If touchpad touches do not work due to a software glitch, then you can try to fix the error in the software yourself. The first method is to reboot the phone. To perform this, hold down the Home and Power on/off buttons for 15-20 seconds. The screen should go dark and then display the Apple logo.

On iPhone 7, the keyboard shortcut for reboot has changed, as the Home button has become a touch button.

Hold down the On/Off button.
Press the Volume Down key.
Hold both buttons until the screen turns off.
Release the keys when you see the Apple logo.

If rebooting doesn't help, try resetting your settings. More effective than a simple reset would be to erase the iPhone, removing all information and then setting up the device as new. Please make a backup in iTunes before performing this operation.

Sensor calibration

Apple devices do not allow users to calibrate the touchscreen. The documentation for tablets and smartphones states that only service center specialists can perform calibration. However, some touchscreen operation parameters can be configured in the latest iPhone models - 6S, 6S Plus, 7, 7 Plus. We are talking about adjusting the sensitivity of 3D Touch.

Open settings, select the “General” section.
Go to the "Accessibility" tab.
Select 3D Touch and adjust the sensitivity of the running screen.

Touchscreen repair or replacement

If the sensor on the new iPhone does not work, and rebooting, deleting Zillow, resetting settings or calibrating does not help, then the right solution would be to contact a service center. There is a high probability that the problem is caused by mechanical problems.

Often users of modern Apple smartphones are interested in what to do if the sensor on the iPhone is faulty, for example, after replacing the glass. And all because the entire operation of mobile devices with touch displays is directly related to the high sensitivity of the screen to pressure, with which you can use the gadget’s functions, view menus, and work with documents. If the sensor stops working, even after replacing the display, you lose the opportunity to fully realize your needs, which are often very necessary to fulfill.

Why does the sensor on a smartphone stop working?

The touchscreen on an iPhone can start to glitch completely spontaneously, for example, after replacing the display or if the smartphone has been dropped. As a rule, the reasons why the touch screen on a particular phone model does not respond to touch or the touch screen works intermittently are associated with mechanical damage to the device. To protect the display from impacts, you can install a protective glass on it or replace the film on it. Without additional protection, for example, if it falls, the touchscreen on the iPhone sometimes begins to freeze or completely fails.

Also, the reasons why the iPhone screen glitches and the touchscreen stops working are the following:

liquid entering the device body
crash after replacing software
failure to comply with manufacturer's requirements when replacing display glass

If you are sure that the iPhone has not been dropped or water has been spilled on it, but it does not respond to touches, does not turn on, or does not respond correctly to presses, then most likely there is a software malfunction that you can fix yourself.

How does a malfunction of the display module manifest itself?

There are several signs that indicate that the sensor is faulty or the touchscreen on the iPhone is not working. These include the following:

lack of sensor response to touches in a certain part of the screen
ignoring any clicks on the display, which indicates that the sensor is lagging
random operation of the gadget after it has been dropped or after replacing the glass (applications and documents open on their own)

Cleaning your smartphone screen

When starting to restore the functionality of a sensor that does not work well, freezes and slows down after replacing the glass or after you dropped it, you must first clean the display of your smartphone. You will not harm the phone in any way, but you will improve the connection, and perhaps the sensor will stop freezing and slowing down. This method will help if the display does not turn on, does not respond to touch, or the sensor periodically glitches.

If the sensor does not work well when buttons are pressed, and it often freezes or slows down, wipe the screen with a soft, lint-free cloth moistened with glass cleaning liquid for various phone models.

How to reboot your phone

If the touchscreen on an iPhone, after replacing the display or for another reason, periodically freezes or the lower part of the sensor does not work, then you can fix the problem by rebooting the phone. When the sensor on your iPhone fails, do the following:

Press and hold the power button and the Home key together for 20 seconds
wait until the device restarts and the Apple logo appears on the display
check if the sensor is working by touching any icon

This instruction will be one of the possible ways to restart your smartphone if the touchscreen does not work or any part of the iPhone sensor stops functioning

Check your accessories if your screen is frozen or won't turn on

There are situations when it is accessories that interfere with the normal operation of the display module and because of them, the iPhone screen of any model becomes dull and glitchy when buttons are pressed on it. For example, if the original protective film was glued to the glass incorrectly, the sensor stops working completely or becomes dull only in the lower part.

In addition, today you can buy any bumper for an iPhone, but not all of them can boast of high quality. If the bumper you purchased blocks the top or bottom of the display, it will interfere with the normal functioning of its module, and the screen will begin to glitch. To understand whether this is the reason why the touch screen does not respond, you need to remove the back cover and test the operation of the touch screen on the phone. If the problem is in the bumper, then the operation of the sensor, which sometimes freezes, will then be restored. If, after removing the accessory, the screen on the iPhone does not stop becoming dull and glitchy, then you need to further look for the cause of the malfunction of the display module.

What to do if the display module is frozen or does not work well

If rebooting the device did not produce results and, as before, the sensor is glitchy, or it does not respond to pressing, then most likely the problem lies not in a software glitch, but in a malfunction of the internal components of the phone and you will have to replace the failed part. In this case, you should contact professional technicians who will diagnose the screen, determine the sensor malfunction and repair the phone.

If the keys periodically glitch and the sensor lags after you dropped the phone, or the display does not respond to pressing, a specialist will first determine the cause of the malfunction and then eliminate it. After diagnostics, the technician will tell you about the condition of the smartphone that was dropped or flooded with water, and why the sensor froze or did not work well. If required, he will carry out a high-quality replacement of the display screen.

In what cases will it be necessary to change the display?

The iPhone screen of any model is regularly exposed to various influences, which is why the touch screen may not respond to touches. Also, scratches on the display can cause the lower part of the sensor to not work. The solution to the problem when the entire screen or part of the iPhone sensor stops working is to replace the glass or install a new module.

You will have to change the display when the sensor malfunctions or displays information incorrectly in the following cases.
